This model interpolates from
a grid of NS atmosphere calculations provided by George Rybicki and Ramesh
Narayan to output a NS atmosphere spectrum. The model grids cover a wide range
of surface gravity and effective temperature, and incorporate thermal electron
conduction and self-irradiation by photons from the compact object. This code
assumes negligible (less than 10^9 G) magnetic fields and a pure hydrogen
atmosphere. A detailed description of the model is given in Heinke et al.
(2006), ApJ in press, astro-ph/0506563 (see also McClintock et al. 2004, ApJ,
615, 402).
